2DB1188Q-13
Diodes Incorporated · Bipolar (BJT) · SOT-89
2DB1188Q-13 from Diodes Incorporated, in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | Base of the PNP transistor; the pin-out drawing shows it as the third lead in the E, C, B order. |
| 2 | C | passive | Collector of the PNP transistor (VCEO -32V, IC -2A continuous); it is also connected to the exposed collector tab. |
| 3 | E | passive | Emitter of the PNP transistor; the pin-out drawing shows it as the first lead in the E, C, B order. |
